MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent N o. 707,671, dated August26, 1902.

Y Application filed August 9.3, 1901. Serial No. 73,007. (No model.)

To all whom, t may concern..

Be it known that I, GEORGE E. ADAMS, a citizen of the United States, anda resident of Glens Falls, in the county of Varren and State of NewYork, have invented a new and Improved Music-Leaf Turner, of which thefollowing is a full, clear, and exact description.

The purpose of this invention is to provide a simple and durable form ofa music-leaf turner adapted for convenient and expeditious attachment tothe music-rack of a piano or a music-rack used in connection with otherinstruments and, furthermore, to so construct the device that but fewparts will be employed and whereby theleaves or sheets of music may befixed in position to a series of music-carrying arms and held inposition after turning until the music-carrying arms are purposelyreleased, which is accomplished by simply touching a device controllingthe same with a linger of a hand, although foot-power may be employed,if desired, and to so construct the music-carrying arms that whenreleased from their retaining device they will automatically assume aposition at the opposite side of the body or frame of the device, thusturning a leaf or sheet to which Ythe arm may be connected.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the ngures.

Figure 1 is a front elevation of the improved device applied to amusic-rack of a piano or organ, a portion of the rack and parts of thedevice appearing in section. Fig. 2 is a vertical section takenpractically on the line 2 2 of Fig. 1. Fig. 3 is a horizontal sectiontaken practically on the line 3 3 of Fig. 1. Fig. L is an enlarged viewof the upper central portion of the rack, illustrating the manner inwhich the sheet-carrying arms are rendered spring-controlled and aresupported on the frame. Fig. 5 is a detail vertical section through thelower portion of the retainingbar for the music-carrying arms and theslide carried by said bar. Fig. 6 is a detail perspective view of thelever which regulates the movement of the bar controlling the movementof the sheet-carrying arms from right to left; and Fig. 7 is a sideelevation of the upper portion of the device at one side, illustratingthe means employed for holding the covers of a book in position upon thedevice.

The frame of the machine consists of an upper cross-bar 10 and a lowercross-bar 1l, together with tubular side bars 12, which are fitted intosuitable openings in the top and bottom bars 10 and 1l at or near theirends. At the lower end of each tubular side bar 12 a footrlS is located,preferably of rubber and of substantially spherical forni, and each footis provided with a shank which extends up into a tubular side bar 12, asis shown at the left in Fig. 1. A spring 14 rests upon the inner end ofthe shank of each foot 13, and an enlargement 15 at the lower end of arod 16 rests upon the upper portion of each spring 14, since a rod 16 isprovided for each tubular side bar 12, and these rods extend out beyondthe upper cross-bar 10 of the frame, terminating, preferably,in a head17 of any desired shape. The object of this construction is to hold theframe of the machine firmly on the music-rack A by reason of the feet13'resting upon the bottom flange of the rack and the heads 17 bearingagainst the upper ange of the rack, the springs 14 being placed undercompression when the device is thus located on the rack. It will beobserved that under such a construction the device may be expeditiouslyand conveniently applied to a rack without detriment thereto in anymanner, as both the feet 13 and heads 17 may loe covered with a softmaterial or may be constructed entirely of a pliable material.

A bar 19 is located vertically and centrally in the frame, extendingfrom the bottom to the top cross-bars thereof, being secured to saidbars by integral brackets 20, as is shown particularlyin Fig.1. Adjacentto and practically parallel with the bar 19 a second bar 21 is located.This bar 21, however, is not attached to the lower cross-bar 11 of theframe, stopping short of the said cross-bar, and at the upper end of thesecond longitudinal bar 21 said bar is attached to a bracket 23, securedto the upper cross-bar 10, so that the longitudinal or vertical bar 2lmaybe swung out- ICO ses

ward from the corresponding bar 19. These two bars are clamping-bars andare adapted to receive between them the central portion 28 of sheets ofmusic 29, as is shown in Fig. 3. The movable binding-bar 21 is held inclamping position with the central portion of the sheets of music by aspring 25, which is secured to the upper face of the lower crossbar 11and has a head 26, which bears against the lower or foot portion of themovable clam ping-bar2l, as is shown in Fig. 1. When this movableclamping-bar is to be carried away from the stationary clam ping-bar 19to release the music, the head of the spring 25 is carried downward intoan opening 24, made in the lower cross-bar 1l of the frame. This spring25 has an upward extension 27, adapted for use in connection With acontrolling-bar, to be hereinafter described.

At each end ofthe upper cross-bar 10 spring- .hooks 30 are located,which extend downward and forward and are adapted to receive betweenthem and the adjacent tubular side bars 12 the boards of a book or thecovers of sheets of music. At the central portion of the upper cross-bar10 a vertical upwardlyextending post 3l is located, (shown in detail inFig. 4,) and on this post a series of sleeves 2 is mounted to turn, eachsleeve being provided with a lateral extension 33. The eX- tensions 33of the sleeves 32 receive the inner ends of leaf-turning bars 34, whichbars at their free or outer ends are provided with clamps 35 to hold thesheets of music, and each clamp, as is shown in Fig. 3, preferablyconsists of two downwardly-extending parallel rods, one rod of a clamppassing down at one face of a sheet and the corresponding clamp at theopposite face of a sheet of music, as is also shown in Fig. 3. Springs36 are attached to the sleeves 32 and are coiled around the saidsleeves, engaging with their extensions 33, and the said springs arecarried also to an engagement with a post 37, also secured upon theupper cross-bar 10, at one side ot' the center, preferably the righthandside. These springs tend to force the music-carrying arms to theleft-hand side of the frame, as is shown in dotted lines in Fig. 1, andwhen the arms are in this position they engage with the upper curvedsection 37a of a reversing-bar 38, mounted to turn in the top and bottomcross-bars ot' the frame and located at the left-hand side of itscenter. The reversing-bar 38 terminates at its lower end in a handle 39,preferably in the form of a crank-arm, so that when all of themusiccarrying arms are at the left-hand side of the frame bymanipulating the handle 39 all of these arms may be carried to theright-hand side of the frame and the springs 36 placed under tension,`and when thisis done the music-carrying arms are held at the right-handside of the frame by a hook 40 at the upper end of a controllingbar 41,usually at, which controlling-bar has sliding movement lin the upper andlower cross-bars of the frame between the center and the right-hand sidebar. A spring 42 is coiled around the upper portion of the saidcontrolling-bar, which spring is attached to the upper cross-bar 10l ofthe frame and to the controlling-bar at a point between its center andupperend, as is best shown in Fig. 1. A slide 43 is mounted upon thefront face of the controlling-bar 41, near its bottom portion, and thespring 27, heretofore referred to, bears against one longitudinal edgeof the slide 43, and in the opposite longitudinal edge of said slideteeth 47 are produced, which are adapted to register with correspondingteeth in the corresponding longitudinal edge of the controlling-bar 4l.The slide 43 is provided at its top and bottom with longitudinal slots44, through which pins 45 extend, attached to the controlling-bar 41. Aspring 46 is secured to the upper end of the slide 43 and to the frontface of the controlling-bar 41. The teeth on the slide or thecorresponding teeth on the controlling-bar 41 are adapted to be engagedby an offset 48 from an angle-lever 49, which angle-lever is shown indetail in Fig. 6. This angle-lever consists of an upper member ct, ayoke section or member ct at the upper portion of the vertical member, ahorizontal section a2 at an angle to the vertical section, and anotherhorizontal or finger section cti at an angle to the intermediatehorizontal section 0.2. This lever 49 is pivoted, by means of a pinpassed through an aperture 50, in the lower portion of the verticalmember of the lever, and when the finger section or member d3 is pressedthe vertical member of the lever has rocking movement on its pivot, therocking movement being controlled by the yoke Ct, the members of whichextend at the front side ot' the slide 43 and at the rear side ot thecontrolling-bar 4l. The said lever 49 is provided at or near thejunction ot' the vertical member@ with the intermediate horizontalmember 0.2 with an arm a4, and to this arm a spring a5 is attached,which spring is also secured to the bottom cross-bar 1l of the frame. v

In the operation of the device, supposing all of the sheet-carrying armsto have been taken over to the right-hand side of the frame and engagedby the hook 40 of the controlling-bar, when the notes upon the sheet ofmusic carried by the uppermost arm have been played the finger member a3of the lever 49 is pressed, whereupon the projection 48 from the lever,which normally engages with a tooth in the controlling-bar, will becarried to a corresponding tooth on the slide 43, enabling the spring 42to carry the controllingbar upward a suftlcient distance to release thehook 40 from the lowermost music-carrying bar, permitting it to becarried by its spring to the left-hand side of the frame, and as soon asthe finger is removed from the said lever 49 the extension 48 of thelever will engage with a second tooth in ythe controllingbar and thespring 46 will draw the slide lOO IIC

IZO

43 upward to such position that its teeth will register with the teethon the controllingbar, as when the controlling-bar iscarried upward bythe spring 42 the pins 45 move up the length of the slots 44 and areprevented from moving farther because of the projection from the lever49 being in engagement with a tooth or" the said slide; but when theprojection 4S of the lever 49 is carried from the slide 43 to a tooth onthe controllingbar 4l the spring 46 will draw thev slide upward, so asto make the teeth in the slide engage with the teeth on thecontrolling-bar, so that when the same action is repeated with referenceto the lever 49 the second lower sheet-carrying arm may be released, andso on. If at any time in order to repeat earlier passages of music it isdesirable to throw one or more of the music-carrying arms to the right,the crank 39 is turned by the tirst linger of the right hand, thusreturning to the right-hand position such arms as had been released, andby pressing with the middle finger ofthe same hand the L-shapedprojection on the bottom of the bar 4l the bar is lowered and theswinging arms engaged by the hook 40, the bar being retained in thislowered position by the hook 48.

Having thus described my invention, I

claim as new and desire to secure by Letters4 Patentl. In a music-leafturner, a frame comprising upper and lower cross-bars, tubular side barsconnecting the cross-bars and a springcontrolled rod located in eachside bar, each rod extending beyond the upper portion of the frame andterminating in a head, and a foot located at the lower end of eachtubular side bar, for the purpose set forth.
